    Abstract: Touch input devices are provided with the capability of sensing a capacitive load in a two-dimensional array while also being able to sense deflection or movement of the input device in multiple different locations under an input pad. A touch input device can beneficially be used in a remote control device and can be used with multiple input buttons or platforms overlaying multiple capacitive touch input regions on a capacitive touch sensor substrate. Movement and position of a capacitive load can be tracked and calculated via output signals from a set of electrodes or other capacitance sensors with irregular shapes, with inconsistent distances from the capacitive load, and which are positioned below variable materials and material compositions. Thus, tracking gestures and taps can be detected using the capacitance sensing devices, and deflection input can be detected using switches or other actuators situated under the capacitance sensing devices.

    Abstract: An earphone comprising: a device housing that defines an internal cavity within the device housing; an acoustic port formed through the device housing and having an opening at an exterior surface of the device housing; an audio driver disposed within the device housing and aligned to emit sound through the acoustic port; a plurality of capacitive pixels disposed within the internal cavity, wherein at least two of the capacitive pixels are disposed radially around the acoustic port and spaced apart from each other by at least 90 degrees; and sensor control circuitry disposed within the internal cavity and operatively coupled to drive the plurality of capacitive pixels at a predetermined frequency to readout a capacitance at each of the plurality of capacitive pixels and determine if the earphone is within an ear of a user

    Abstract: Touch electrode architectures for reducing the occurrence of negative pixels in mutual capacitance touch sensor panels that are caused by poorly grounded objects are disclosed. A touch electrode architecture can utilize mutual capacitance unit cells, each of which include a drive electrode, a sense electrode, and one or more ground bars. The one or more ground bars can provide an increased capacitive path to ground for a poorly grounded finger, which can result in a larger reduction in mutual capacitance between the drive and sense electrodes, improving touch detection. In addition, the increased capacitive coupling between the object and ground reduces the amount of charge that couples back onto nearby sense electrodes, which can reduce the negative pixel that can occur at those electrodes and reduce the number of touch detection errors. The one or more ground bars can be formed in the same layer as the drive electrode.
